Another triumph for CCTV! I know that it has it's detractors and have some sympathy with the anti-surveillance society arguement. However, if Griffiths hadn't been spotted on camera with one of his victims, he'd still be out on the streets. Of course, he hasn't been found guilty yet but the evidence against him seems to be stacking up. I wonder if the Yorkshire Ripper would have had such a long run if the same level of surveillance had been available back then? It was pure chance that he was finally captured - a diligent copper checked out the number-plate of a parked car one night and found it to be false. As for the girls being prostitutes, I suppose it is worth reporing their profession in order to put the crime into some sort of context - Griffiths preyed on prostitutes as they are the most vulnerable women in society and their way of working presented him with the opportunity.
